Purchased from Co. 7 two years ago and was pick of the litter out of five. Has fan installed as per Sky and Telescope article to help break up boundry layer of air over primary. Cooldown wasn't ever much of an issue. Have built a more functional mount utilizing a cradle so that OTA can slide or rotate. Proper balance can be achieved in seconds even with the heaviest EPs.Bearings and cradle are made of cherry. Asking price is 400.00. 9X50 RACI Finder not included. I will not ship this scope but am willing to meet buyer within reasonable driving distance of Baltimore / Washington DC Metro area.
